thanks for answering.
Everything is working except the Link to a detailed Page.

When i am inserting the $Link it will give me nothing back.

As i know it from other PHP Applications i should be able to link to the detailed Page and add an ID or Name to $_GET it from the Database, maybe you can explain how to get the Link going and how to receive Data on the detailed Page.

This works just as sam described using the $Link variable. You can't use IDs as links or anything else, you need to use the variable that is provided. You should only need one Location holder and make all the locations children of this page.
